Fertilizer help???

Ok, so I started germin my seeds on Oct 1.. They sprouted, and by the 7th they came off the windowsill and moved to their home in the closet. I have them in clear plastic solo cups... It is the 14th adn I have a couple of sets of leaves already on some of them... My question is when should I start fertilizing??? I have chickens and hope to use chicken shit for my fertilizer, diluted heavy of course. I don't want to burn them up... Any suggestions no using that as a fertiler would help....

What's your setup like? I'm guessing soil, right? and if they are in soil already, the nutes in the soil shoud be ok for the first 2-3 weeks, and add fert. as soon as you start to see a little yellowing, your plants will let you know. Got any baby pics?

No, my camera is F'ed up right now!!! The really nice looking ones have 2 set of leaves already!! I got the seeds from holland, they were free with my NL purchase. I am waitin to germ those until I get my bigger lights.

Any suggestions using chicken shit??? I know it is loaded with nitrogen.. I have used peruvain sea bird guano, but it is expensive and the girls live in the yard

I'm a hydro guy myself. So goodluck witht the bird crap. Peace : ]
